Question

As you can see from the title I basically want to update a plist. Actually the app user will type his data in data fields and I will take them and save them in a plist. He can add as many objects as he likes.
I have tried a huge number of different codes for that staff and none of them works. First of all take a look at my plist (I am presenting you the xml code so you can understand it)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <array>
        <dict>
            <key>name</key>
            <string>TEST</string>
            <key>code</key>
            <string>TEST</string>
            <key>longitude</key>
            <integer>22</integer>
            <key>latitude</key>
            <integer>10</integer>
         </dict>
    </array>
</plist>

That was just a simple entry. Now here is the lates code I have used but I had no luck at all

NSMutableDictionary *newBuilding = [NSMutableDictionary alloc];
    [newBuilding setValue:@"Test1" forKey:@"name"];
    [newBuilding setValue:@"Test2" forKey:@"code"];
    [newBuilding setValue:@"10" forKey:@"latitude"];
    [newBuilding setValue:@"20" forKey:@"longitude"];

    NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);

    NSString *documentsPath = [paths objectAtIndex:0];

    NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"BuildingsInfo.plist"];

    NSMutableArray *newArray = [NSMutableArray arrayWithContentsOfFile:plistPath];

    if (nil == newArray) {
        newArray = [[NSMutableArray alloc] initWithCapacity:0];
    }

     [newArray addObject:newBuilding];
 [newArray writeToFile:plistPath atomically: YES];

 }

Can anybody spot any mistake? I have written it a lot of times, I have checked every token but I have found no mistakes. I cannot understand why I does not want to work!

Thanks a lot guys

For what it’s worth, you never initialized newBuilding.
